  1. Uses & Benefits. Find information on the wide variety of plastics used in hundreds of household and consumer products. Plastics enable sustainable, durable, long-lasting design and construction in homes, buildings, and infrastructure like bridges.; In automotive design, plastics have contributed to a multitude of innovations in safety, performance and fuel efficiency.
  2. Oct 23,  · Plastics and natural materials such as rubber or cellulose are composed of very large molecules called polymers. Polymers are constructed from relatively small molecular fragments known as monomers that are joined together. Wool, cotton, silk, wood and leather are examples of natural polymers that have been known and used since ancient times.
  3. Plastics are typically organic polymers of high molecular mass and often contain other substances. They are usually synthetic, most commonly derived from petrochemicals, however, an array of variants are made from renewable materials such as polylactic acid from corn or cellulosics from cotton linters.
  4. From plastic waste to new chemical products. Plastics do have proven benefits during their use phase – for example preservation of food loss in packaging applications, lightweight construction of vehicles, and building insulation. Plastic waste, however, and in particular plastic waste in the context of marine littering, is a major global.
  5. The structure of polypropylene can serve as an example; here attached to every other carbon atom is a pendant methyl group (CH 3): The other category of plastics is made up of heterochain polymers. These compounds contain atoms such as oxygen, nitrogen, or sulfur in their backbone chains, in addition to carbon.
  6. Decomposition/depolymerization – The molecular bonds of used plastic are broken, resulting in molecules (monomers) from which plastics are made. Conversion – The molecular bonds of used plastic are broken and recombined, resulting in hydrocarbons and chemical feedstocks similar to products made by petroleum refining.
  7. Sep 09,  · Synthetic polymers are prepared by a chemical reaction, often in a lab. Examples of synthetic polymers include PVC (polyvinyl chloride), polystyrene, synthetic rubber, silicone, polyethylene, neoprene, and nylon. Synthetic polymers are used to make plastics, adhesives, paints, mechanical parts, and many common objects.
